Robots are not failing in a way that emulates some teenager in his 90s shitbox doing donuts in the street. They are failing in a way that emulates some middle aged middle manager in her $50k SUV who stops at a cloverleaf because the traffic is intimidating.
The latter case is far more frustrating to most people because the person or robot is inconveniencing everyone not willfully, but out of their own inability to do something the rest of the driving public can do fine whereas the teenager doing donuts can be more easily empathized with by most people in a Falling Down sort of way. And unlike a semi truck that simply can't move fast enough to not inconvenience others or an elderly person taking a long time to go up some stairs the robo-car and incompetent driver don't have what most people consider a good excuse for their behavior.
